FIELD OF THE INVENTION

The present invention relates to a device for recording data on a diskas accommodated in a cartridge.

BACKGROUND OF THE INVENTION

A recording medium is already in use which comprises a disk 60accommodated in a rectangular cartridge 6 formed at a side portionthereof with a window 62 for 10 exposing the disk as shown in FIGS. 20,(a) and (b) (see JP-A No. 298799/1993). The window 62 is opened oralternatively closed with a shutter 61 which is slidable on thecartridge 6. The shutter 61 has a side wall formed with a small hole 63.The cartridge 6 has a first slit 64 formed in a side wall thereof wherethe shutter 61 is provided, and a second slit 65 in another side wallthereof opposite to the shutter 61. The shutter 61 is engaged with thecartridge 6 by a lock mechanism (not shown). When the cartridge 6 isinserted into a recording device, an unlocking piece 29 in the recordingdevice advances into the first slit 64, unlocking the shutter 61 andpushing the shutter open.

FIG. 21 is a side elevation showing the relationship in position betweena mechanical deck 100 for receiving the cartridge 6 as inserted and acabinet 4 housing the deck 100. The cabinet 4 has a front opening whichis provided with a pivotal panel 42 pivoted at its upper end to thecabinet 4. The cartridge 6 is inserted into the mechanical deck 100while opening the pivotal panel 42.

FIG. 17 is an exploded perspective view of the mechanical deck 100. Inthe following description, the side of the deck 100 at which thecartridge 6 is delivered from the deck 100 will be referred to as the“delivery side,” the direction in which the cartridge advances as“forward,” and the direction in which the cartridge is delivered as“rearward.” The mechanical deck 100 comprises the combination of aninner holder 2 into which the cartridge 6 is inserted from the frontopening, and an outer holder 3 covering the upper side of the innerholder 1. The combination is mounted on a chassis 1, which is secured tothe bottom wall of the cabinet 4.

A pickup 75 and turntable 76 are provided on the chassis 1 as wellknown. A head lever 7 biased downward and carrying a recording head 70at its distal end is attached by a bracket 71 to the pickup 75. The headlever 7 is moved upward and downward by a head lift mechanism (notshown) mounted on the chassis 1.

A kickout lever 8 having a cutout 86 formed in a peripheral edge portionthereof is pivotally supported on the upper side of the inner holder 2.Disposed forwardly of the kickout lever 8 is a stopper piece 17 providedupright on the chassis 1. The kickout lever 8 is biased by a tensionspring 85 toward the cartridge delivery side into contact with a stopper210 on the upper side of the inner holder 2.

The kickout lever 8 has one end bent downward to provide a push lug 80pushable by the cartridge 6. The outer holder 3 is provided over theinner holder 2. Pins 220, 220 projecting from each of opposite sidewalls of the inner holder 2 are fitted in cam slots 30 formed obliquelyin a side wall of the outer holder 3. Projections 37 project outwardfrom each of opposite side walls of the outer holder 3. One of theseside walls has a grip 31 projecting outward and to be pulled by the userwhen the cartridge 6 is to be delivered.

Each of opposite side walls of the chassis 1 has guide grooves 18 forthe respective projecting pins 220 to fit in and horizontal slots 19 forthe respective projections 37 to fit in. Each guide groove 18 has ahorizontal portion 18 a and a vertical portion 18 b continuoustherewith. A spring retainer 38 projects from the rear end of one sidewall of the outer holder 3.

FIGS. 19(a) and (b) are side elevations of the mechanical deck 100. Atension spring 9 extends from the spring retainer 38 to the chassis 1,biasing the outer holder 3 toward the direction of insertion of thecartridge 6.

FIGS. 18(a) and (b) are plan views of the mechanical deck 100. When thecartridge 6 is inserted into the inner holder 2 in a standby state shownin FIG. 18(a), the cartridge 6 pushes the push lug 80 against thetension spring 85, rotating the kickout lever 8 counterclockwise,whereby the cutout 86 of the lever 8 is opposed to the stopper piece 17,allowing the inner holder 2 to advance a distance corresponding to thedepth of the cutout 86.

The inner holder 2 is provided inside thereof with a projecting piece(not shown) fittable in the second slit 65 of the cartridge 6. When therear end of the second slitted portion 65 pushes the projecting piece onthe inner holder 2, each projecting pin 220 on the inner holder 2 in thestate shown in FIG. 19(a) slidingly moves along the horizontal portion18 a of the guide groove 18 to push the cam slotted portion 30 of theouter holder 3. The outer holder 3 pushed by the inner holder 2 has itsprojections 37 fitted into the respective horizontal slots 19 of thechassis 1 and slidingly moves horizontally.

Upon each projecting pin 220 reaching the front end of the horizontalportion 18 a, the inner holder 2 descends, and the pin 220 reaches thelower end of the vertical portion 18 b as seen in FIG. 19(b). Thecartridge 6 descends while holding the kickout lever 8 in its pushedposition. The inner holder 2 lies on the chassis 1 with the cartridge 6placed therein. The outer holder 3 biased forward by the tension spring9 biases the inner holder 2 forwardly downward through the projectingpins 220, biasing the cartridge 6 toward the turntable 76.

However, the conventional device has the following problems.

1. The chassis 1 is fixed to the cabinet 4, and the inner holder 2 ismovable upward and downward above the chassis 1. Since none of partssuch as pickup 75 can be provided in the space for the inner holder 2 topass through for upward and downward movement, a dead spacecorresponding to the amount of up-down movement of the inner holder 2 isformed inside the cabinet 4. The space presents an obstacle to areduction in the thickness of the device.

2. The cartridge 6 is horizontally inserted into the cabinet 4 and thendescends. If the distance of descent is small, therefore, the pivotalpanel 42 is pushed open once by the cartridge 6 moving horizontally asshown in FIG. 22(a) and is likely to be thereafter held semiopen by thecartridge 6 as loaded in position as shown in FIG. 22(b). The semiopenpanel 42 has a poor appearance, making the user feel as if the cartridge6 were caught by an obstacle in the course of descent.

To eliminate this semiopen state, it is necessary to prevent the contactof the lower end of the pivotal panel 42 with the upper surface of thecartridge 6 by increasing the distance of descent of the cartridge 6 orlengthening the distance between the panel 42 and the mechanical deck100. In either case, the device then becomes greater in size. Furtherthere is a need to provide a mechanism for opening the panel 42 when thecartridge 6 is to be delivered. This requires a complex mechanism.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a compacted recordingdevice of reduced thickness for use with a cartridge as loaded therein.

An inner holder 2 is attached to a cabinet 4, and a chassis 1 positionedbetween the inner holder 2 and the cabinet 4 is movable upward anddownward relative to the inner holder 2.

In this case, a space 44 for accommodating a pickup 75, etc. needs to beprovided on the rear side of the chassis 1 (see FIG. 15). The chassis 1moves upward and downward in this space 44. Thus, the space 44 foraccommodating the pickup, etc. and the space for the upward and downwardmovement of the chassis 1 can be both provided under the chassis 1 toeffectively utilize the interior space of the device. This reduces thethickness of the device.

The inner holder 2 to be loaded with the cartridge 6 does not moveupward or downward. A pivotal panel 42 is held completely opened bycontact with the upper surface of the cartridge 6 as loaded in the innerholder 2. Unlike the prior art, therefore, the invention eliminates thelikelihood that the pivotal panel 42 will be held semiopen. Furtherbecause the pivotal panel 42 is not closed with the cartridge 6 loadedin position, it is possible to shorten the distance of up-down movementof the chassis 1 and also the horizontal distance from the pivotal panel42 to the mechanical deck 100.

A label bearing the name of data recorded is often affixed tothe rear end face of the cartridge 6, enabling the user to identify therecorded data, with the cartridge 6 inserted in the cabinet 4.

[Detailed Description of Mechanical Deck]

FIG. 3 is an exploded perspective view of a mechanical deck 100positioned inside the cabinet 4. The deck 100 comprises an inner holder2 for receiving the cartridge 6 as inserted therein, and an outer holder3 provided over the inner holder 2 and slidable in the direction ofinsertion of the cartridge. The outer holder 3 and the inner holder 2are positioned over the chassis 1. The chassis 1 has a pickup 75 and aturntable 76 and is further provided with pins 77, 77 for supporting thebottom of the cartridge 6.

With the device of the present embodiment, the inner holder 2 to beloaded with the cartridge 6 is fixed as attached to the cabinet 4 aswill be described below, and the chassis 1 moves upward and downwardrelative to the inner holder 2.

The chassis 1 is provided at its opposite sides with support walls 11,11 each having inward projections 10, 10. The projections 10, 10 fit inthe inner holder 2 and the outer holder 3. An opening 12 for exposingthe pickup 75 is formed in the chassis 1 and positioned rightward of itscenter. Cutouts 13, 13 and holes 14, 14 are formed in the respectivecorners of the chassis 1. As will be described later, the inner holder 2is attached to the cabinet 4 through the cutouts 13, 13 and the holes14, 14.

A head lever 7 is attached as biased downward to the pickup 75 by abracket 71, and carries a recording head 70 at its distal end.

The outer holder 3 shown in FIG. 3 is formed by bending opposite sideedges of a metal plate. Cam slots 30, 30 slanting downward along thedirection of insertion of the cartridge are formed in each of side wallsof the holder 3. The outer holder 3 has a projection 32 inwardlyprojecting from a front end portion thereof, and a grip 31 projectingoutward from the left side wall thereof. The grip 31 is pulled towardthe user for delivering the cartridge 6 from the deck.

A kickout lever 8 is pivotally supported at its base end on the uppersurface of left end portion of the inner holder 2. The kick lever 8 hasa free end bent downward to provide a push lug 80, which extends througha circular-arc slot 22 formed in the inner holder 2 to the insidethereof. As will be described later, the push lug 80 is pushed by thefront end of the cartridge 6 when the cartridge 6 is inserted. A tensionspring 85 extends from the outer holder 3 to the kickout lever 8,pressing the lever 8 into contact with a stopper 33 provided on theouter holder 3 in a standby state wherein no cartridge 6 is inserted inthe inner holder 2.

[Head Lever Drive Mechanism]

The inner holder 2 has an aperture 20 for permitting the recording head70 to pass therethrough, and is formed on its upper surface with lugs21, 21 positioned to the front of the aperture 20. FIG. 4 is a sideelevation of the deck 100 as it is seen from the direction of arrow C inFIG. 3, and FIG. 5 is a perspective view of a head drive lever 5.

With reference to FIG. 5, the head drive lever 5 comprises a contactplate 50 having pivots 51, 51 projecting outward from the base ends ofopposite side portions thereof and supported by the respective lugs 21,21. The contact plate 50 has a first contact piece 52 projecting fromone of the plate side portions and in contact with the upper surface ofthe inner holder 2, and a second contact piece 53 projecting from theother side portion, raised from the plate 50 and in contact with theouter holder 3.

As shown in FIG. 4, the outer holder 3 is formed with a protrusion 34 solocated as to come into contact with the second contact piece 53. Whenthe second contact piece 53 is brought into contact with the protrusion34 with the sliding movement of the outer holder 3, the head drive lever5 is pushed up to pivotally move upward. The head lever 7 is biaseddownward about the pivot of the head lever 7 on the bracket 71 aspreviously stated, and the free end of the head lever 7 contacts thecontact plate 50 of the head drive lever 5. When the deck 100 is in itsstandby position, the head drive lever 5 is in a raised position,permitting advance of the cartridge 6 as seen in FIG. 13(b).

[Arrangement of Inner and Outer Holders and Chassis]

FIG. 6 is a perspective view of the inner holder 2, FIG. 7 is a bottomview of the same as it is seen from below upward, FIG. 8 is a front viewof the same as it is seen from the direction of arrow A in FIG. 6, andFIG. 9 is a left side elevation of the same as it is seen from thedirection of arrow G in FIG. 6. The chassis 1 indicated in a chain linein FIG. 7.

As shown in FIG. 6, each of the side walls of the inner holder 2 hasvertical slots 23, 23 opposed to the cam slots 30, 30 of the outerholder 3, and horizontal slots 24 having fitted therein the projections32 of the outer holder 3 for guiding the horizontal sliding movement ofthe outer holder 3. When the inner holder 2 is loaded with the cartridge6 and also when it is vacant, the aperture 20 of the inner holder 2 isnot covered with the outer holder 3. Legs 25, 25 extend downwardrespectively from the front and rear ends of side wall of the innerholder 2 and have lower ends bent outward to provide mount portions 26.A threaded bore 26 a is formed in each mount portion 26 centrallythereof.

As shown in FIGS. 7 and 8, the opposite side walls of the inner holder 2are bent inward at their lower ends to provide support plates 27, 27 forsupporting the cartridge 6 at its bottom. One of the support plates 27has protuberances 28, 28 protruding toward the chassis 1. Theprotuberances 28, 28 are in register with the respective holes 14, 14 ofthe chassis 1.

With reference to FIGS. 6 and 8, the midportion of one side wall of theinner holder 2 is inwardly bent to provide an unlocking piece 29 whichis movable into the first slit 64 of the cartridge 6. A spring 66 havinga crest facing inward is provided inside the inner holder 2 to the rearof the unlocking piece 29.

As the cartridge 6 is inserted into the inner holder 2, the unlockingpiece 29 shown in FIG. 20(a) advances into the first slit 64, unlockingthe shutter 61 and pushing the shutter 61 open. When the cartridge 6 ispulled out of the holder 2, the spring 66 fits into the small hole 63 inthe shutter 61, closing the shutter as the cartridge 6 is moved towardthe delivery direction. When the cartridge 6 is further pulled out as itis, the shutter 61 is released from the fitting engagement with thespring 66.

Inwardly projecting from the front end of the left side wall of theinner holder 2 shown in FIG. 9 is an engaging piece 200 fittable in thesecond slit 65 of the cartridge 6.

FIG. 10 is a plan view of the mechanical deck 100 as attached in itsstandby position to the cabinet 4, and FIG. 11 is a front view showingthe deck 100 as it is seen from the direction of arrow B in FIG. 10. Thekickout lever 8 is biased rearward by the tension spring 85, with thepush lug 80 in contact with the rear edge of the circular-arc slottedportion 22 of the inner holder 2. The stopper 33 of the outer holder 3is in contact with the kickout lever 8, which restrains the outer holder3 from advancing.

Further as shown in FIG. 13(a), the projections 10 of the chassis 1 arepositioned at the lower ends of the respective cam slots 30 of the outerholder 3 and are in the lowermost position remotest from the innerholder 2. The head drive lever 5 is in its raised position as statedabove, holding the head lever 7 lifted as seen in FIG. 13(b).

[Chassis Provided in Cabinet]

FIG. 15 is a side elevation in section showing the cabinet as it is seenfrom the direction of arrow E in the plan view of FIG. 10, and FIG. 16is a side elevation in section of the same as it is seen from thedirection of arrow F in FIG. 10. As shown in FIG. 15, the cabinet 4 hasa boss 41 projecting therefrom and extending through the cutout 13 ofthe chassis 1 from therebelow upward. The inner holder 2 is supported bythe boss 41. A screw 40 extends through the boss 41 from the undersideof the cabinet 4 and is screwed into the mount plate 26 to fasten theinner holder 2 to the cabinet 4.

Further as seen in FIG. 16, the protuberance 28 of the inner holder 2 isin register with the hole 14 in the chassis 1, and fastened to thecabinet 4 with a screw 40 extending upward from the underside of thecabinet 4.

With the device of the present embodiment, the inner holder 2 is fixedto the cabinet 4, and the chassis 1 is movable upward and downward. Datais recorded on the disk, with the chassis 1 in a completely raisedposition.

[Insertion of Cartridge]

When the cartridge 6 is placed onto the support plates 27 of the innerholder 2 and pushed into the holder 2, with the mechanical deck 100 inits standby position shown in FIG. 10, the front end of the cartridge 6pushes the push lug 80 of the kickout lever 8, rotating the lever 8counterclockwise. The cartridge 6 slides along with the engaging piece200 of the inner holder 2 fitting in the second slit 65 of the cartridge6 (see FIG. 9).

FIGS. 12(a) and (b) are plan views showing parts during the insertion ofthe cartridge 6 to its loaded position. With the cartridge 6 completelypushed in as seen in FIG. 12(a), the rotation of the kickout lever 8releases the stopper 33 therefrom, causing the outer holder 3 to beadvanced by the tension spring 85 as shown in FIG. 12(b). In this state,the shutter 61 on the cartridge 6 has already been opened by theunlocking piece 29, exposing the disk from the cartridge 6.

[Data Recording and Reproduction]

The advance of the outer holder 3 releases the second contact piece 53of the head drive lever 5 from the protrusion 34 of the outer holder 3,allowing the lever 5 to move down as shown in FIG. 14(b) and thedownwardly biased head lever 7 also to pivotally move downward to bringthe recording head 70 closer to the disk through the aperture 20.

Further as seen in FIG. 14(a), the chassis 1 having its projections 10fitted in the respective cam slots 30 is biased upward and raisedvertically upward along the vertical slots 23 of the inner holder 2 bythe advance of the outer holder 3. The cartridge 6 has a thickness ofabout 5 mm. The upward stroke length of the chassis 1 is set to adistance smaller than the thickness of the cartridge 6 by the presentapplicant. The chassis 1 stops upon the projections 10 reaching theupper ends of the cam slots 30. The turntable 76 fits to the disk insidethe cartridge 6, making it possible to record data on the disk.

The outer holder 3 is biased forward by the tension spring 85 andtherefore forces the projections 10 to press the turntable 76 on thechassis 1 against the cartridge 6, whereby the disk 60 in the cartridge6 is prevented from backlashing relative to the turntable 76.

When the cartridge 6 is in its loaded position, the pivotal panel 42shown in FIG. 2(b) is left open with its rear end portion bearing on theupper surface of rear end portion of the cartridge 6 as previouslystated. This enables the user to recognize the data name on the rear endface of the cartridge 6.

When the cartridge 6 is inserted into the device, the recording head 70descends. The disk can be played back when no current is passed throughthe recording head 70.

[Delivery of Cartridge]

To deliver the cartridge 6 from the loaded position shown in FIG. 12(b),the grip 31 of the outer holder 3 is pulled out by hand against thetension spring 85. The protrusion 34 of the outer holder 3 comes intocontact with the second contact piece 53 of the head drive lever 5 toraise the head lever 7 as seen in FIG. 13(b).

From the state shown in FIG. 14(a), the projections 10 of the chassis 1fitting in the respective cam slots 30 are urged downward, moving thechassis 1 downward along the vertical slots 23 and moving the turntable76 away from the cartridge 6.

When the outer holder 3 is further pulled out, the stopper 33 moves outof the path of pivotal movement of the kickout lever 8 as shown in FIG.12(a), permitting the tension spring 85 to rotate the lever 8 clockwise.The push lug 80 of the lever 8 delivers the cartridge 6 from the innerholder 2 under the action of the tension spring 85.

Since the inner holder 2 is attached through the chassis 1 to thecabinet 4, there is no need to give a large upper surface to the innerholder 2.

Furthermore, loading of the cartridge 6 into the inner holder 2automatically brings the head lever 7 close to the cartridge 6, wherebythe head 70 is made ready to record data on the disk. Accordingly, thereis no need to additionally provide a mechanism for moving the head lever7 upward and downward. This results in a reduction in the number ofcomponents.

Further with the mechanical deck 100 of the preset device, the tensionspring 85 biases the turntable 76 toward the cartridge 6 for recordingand pushes the cartridge 6 for delivery from the deck. Thus, the singletension spring 85 acts to deliver the cartridge 6 from the device and tohold the cartridge 6 in the recording position. This serves to reducethe number of components.

Although portions of the cabinet 4 are inserted through the holes 14 orcutouts 13 according to the present embodiment, the legs 25 of the innerholder 2 may alternatively extend through the holes 14 or cutouts 13.
